How Much Monthly Income Will My 401(k) Provide in Retirement?

Introduction: The Real Human Problem

For pre-retirees in Sandy and Draper, the most critical question is how their 401(k) balance translates into monthly income. Transitioning from saving money to drawing it down can be intimidating. This calculator helps you convert your projected lump-sum 401(k) balance into a sustainable monthly payout.

Planning for your future in the Wasatch Front requires a strategy that accounts for local cost of living and specific lifestyle desires. Whether you enjoy skiing at Alta, hiking in the Cottonwood canyons, or raising a family in South Jordan, your financial roadmap should be built around your life—not just a generic set of numbers.

How This Calculator Works (Simply Explained)

To get the most out of this tool, it is helpful to understand the key inputs that drive the results:

Current Balance: The starting value of your 401(k) today.
Expected Return: The portfolio growth rate before and during retirement.
Withdrawal Rate: The percentage of the portfolio you plan to withdraw annually (e.g., 4%).

By adjusting these inputs, you can model different financial scenarios to see how subtle shifts in your savings rate or portfolio return can impact your long-term wealth.

Scenario: The Power of Planning in Action

Consider this hypothetical scenario: A 55-year-old pre-retiree in Draper, UT, has a hypothetical $750,000 in their traditional 401(k). By contributing a hypothetical $1,000 monthly for another 10 years and assuming a hypothetical 7% return, they project a balance of $1.5 million at age 65. Under a standard hypothetical 4% withdrawal rate, the calculator shows a monthly retirement income of $5,000 (before taxes). Planning for this taxable ordinary income is key.

This scenario highlights how consistent actions and a clear timeline can remove the guesswork from your finances, transforming abstract goals into a concrete roadmap.
